What You're Buying

This is the front left complete strut assembly, US driver's side, for the 2001–2007 Toyota Sequoia. The first-generation Sequoia sits on the XK30/XK40 body-on-frame platform and runs a coil-over MacPherson strut at each front corner for all seven model years. Power comes from the 4.7L 2UZ-FE V8 across the board: SR5 and Limited trim, 2WD and 4WD.

The unit arrives fully pre-assembled. Coil spring, upper mount bearing, dust boot, and jounce bumper come pre-compressed as one piece, so no spring compressor is needed. That removes the riskiest step of a strut job for a home mechanic. The full listing is on the Front Left Complete Strut Assembly for 2001-2007 Toyota Sequoia page at koeep.com.

Spec Matrix and OEM Cross-Reference

Match these numbers against your old unit or a parts diagram before you order. The assembly replaces Toyota OEM 48510-0C011 (2001–2004) and 48510-A9600 (2005–2007), covers pairing number 48510-0C012, and cross-references the aftermarket numbers 171348L for the driver's side and 171348R for the passenger side.

The 171348L and 171348R numbers also map to equivalent assemblies from Monroe, KYB, TRQ, and Suncore. Verify the seller's certification if you cross-shop: counterfeit suspension components have been flagged on open marketplace channels.

2026 Materials and Certification

Test standards behind the unit

For the 2026 service cycle, the assembly is validated against four benchmarks:

• SAE J1202 suspension fatigue testing: at least 100,000 full-stroke rebound-to-compression cycles with no pressure loss and no seal weep.
• IATF 16949:2016 manufacturing certification.
• ASTM B117 salt-spray corrosion testing, 96 hours minimum, on the zinc-nickel plated outer tube.
• ASTM D2000 EPDM rubber classification, plus ISO 21308 chassis-construction guidance for load-path alignment.

What changed versus the 2001 originals

The outer-tube seal is now a high-temp EPDM/Nitrile composite rated from -40°C to +120°C. It outlasts the 2001-era NBR rubber, and the gap shows fastest on Arizona and Texas Sequoias that sit through long heat-soak exposure.

The piston rod is micro-polished SAE 9254 high-carbon steel with a surface finish of Ra ≤ 0.10 μm. The tighter finish cuts seal wear and oil aeration, the two problems behind the morning sag reported on 2001–2004 Sequoias approaching 200,000 miles.

Twin-Tube Design and Electronics Compatibility

The strut keeps the twin-tube, gas-over-hydraulic architecture Toyota specified for the 2UZ-FE platform. The coil spring is wound from Scrutton-enamelled SAE 9254 high-carbon steel, and the upper mount bearing ships packed with lithium-complex EP2 grease rated to -40°C. That grease spec targets the cold-weather squeak-on-steer reported on 2005–2007 Sequoias with original mounts past 150,000 miles.

Nothing in the unit is electronic. It is a passive hydraulic component with zero modules, so it works with 2026 diagnostic protocols: OBD-II, J-2284-4, and K-Line legacy scan tools, with no CAN transceiver interference. If your 2006 Sequoia Limited carries the factory rear air kit, this front strut swaps in with no air-line or compressor interaction.

DTC Mapping for the Sequoia Chassis

A passive MacPherson strut does not generate its own trouble codes. That separates it from electronically damped setups such as GM units (C1031-C1037 chassis codes) or Toyota's X-REAS. Wear shows up indirectly, through the ABS/VSC module.

When the left front strut loses rebound damping, the wheel loses clean road contact. Under sustained corner-load transfer, the system can log these Toyota chassis codes:

• C1201-C1205: VSC/TRAC control communication faults.
• C1225-C1228: wheel speed sensor plausibility errors.
• C1221/C1222: ABS motor relay and light control. Watch for these when a binding mount bearing creates steering-angle deviation.
• C1281/C1282: VSC system brake-pressure logic.

One filter before you blame the strut: a P0400-P0499 EGR-family code with no C-codes points to the exhaust and EGR circuit first.

The reliable diagnostic path is mechanical, in this order: a static ride-height check, a rebound-recovery bounce test where each corner settles within 1.5 strokes, and a visual check for hydraulic film weep at the outer tube seal. Never close this diagnosis with a scan tool alone.

Left Side, Right Side, or Full Front Kit

This listing covers the left side only. For the passenger corner, order the matching Front Right Complete Strut Assembly for 2001-2007 Toyota Sequoia, which cross-references 171348R. A matched pair keeps damping and ride height even across the axle.

If both fronts are worn, and on trucks past 120,000 miles they usually are, the Front Complete Strut Assembly Kit for 2001-2007 Toyota Sequoia covers both sides in one order. The Steering & Suspension collection holds the full catalog of related parts.

Also running a Tundra? The blog guide to the Complete Front Steering & Suspension Kit for 2003-2006 Toyota Sequoia & Tundra walks through that kit for both trucks.
